It must be one of the following: (da0:ahc0:0:0:) parity error during Data-Out phase. (da0:ahc0:0:0:) parity error during Data-In phase. (da0:ahc0:0:0:) parity error during Command phase. (da0:ahc0:0:0:) parity error during Message-Out phase. (da0:ahc0:0:0:) parity error during Status phase. (da0:ahc0:0:0:) parity error during Message-In phase.

I've never seent the aic7xxx chips lie about parity errors. It could also be something like a cold solder joint on the 2940U2W. -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
